Alarm Management: Getting the Most Out of your Yokogawa Control System
Recording Date: April 2021
Yokogawa has a long and rich history of “firsts” in the world of distributed control systems (DCS). They were one of the first suppliers to include alarm shelving, for example, long before it became required alarm management functionality per the ISA-18.2 / IEC 62682 standards. Despite this, many Yokogawa users don’t leverage the alarm management capabilities that are available to them. The purpose of this presentation is to discuss alarm management tools and capabilities that can be used to comply with the ISA-18.2 / IEC 62682 alarm management lifecycle, to reduce unwanted shutdowns (trips), reduce risk, and improve operator effectiveness. Highlights include discussion of how to analyze alarm system performance, perform rationalization, use eclipsing, alarm shelving, load shedding, alarm flood suppression, and present “Alarm Help” to the operator (alarm response procedures). Examples will be shown from CAMS, SILAlarm, exaquantum ARA and AMD, exapilot, and exaplog.
